As described above, each linkedfile may be provided with an annotation that includes various types ofinformation about the file. Annotation information may include suchthings as a title for the file, who created the file, when the file wascreated, what is the relationship of the file to an anchor file, etc.Thus, for example, GUI control 26 may enable a user to locate all fileslinked to an anchor file that relate to a user's grandparents and/orthat were created prior to 1995.

GUI control 28 is configured to allow a user to designate various rightsregarding an anchor file and files linked thereto. For example,according to some embodiments of the present invention, GUI control 28allows a user to grant access rights to selected users that allow theselected users to link other files to an anchor file (e.g., anchor file12 a). According to some embodiments of the present invention, GUIcontrol 28 may be configured to allow a user to assign privacy rights tofiles linked to an anchor file, wherein the privacy rights specify whocan access a file linked to an anchor file. According to someembodiments of the present invention, GUI control 28 may be configuredto allow a user to assign privacy rights to files linked to an anchorfile, wherein the privacy rights specify who can access files associatedwith a file linked to an anchor file.

A digital archive according to embodiments of the present invention isnot required to have a user interface with all of the above-describedfeatures. For example, a user interface may include fewer GUI controlsor more GUI controls than illustrated in FIG. 1. Moreover, one or moreof the various functions described above may be performed in other waysin lieu of the use of GUI controls. For example, a user interfaceaccording to some embodiments of the present invention may include menusthat perform one or more of the above-described functions. In addition,files displayed within an user interface according to some embodimentsmay be configured to be “clickable” by a user in order to initiate oneor more of the above-described functions (e.g., a displayed file isconfigured such that a user may position a mouse pointer over thedisplayed file and press a mouse button to initiate certain functions).

Exemplary operations for linking files in a digital archive, accordingto some embodiments of the present invention, will now be described withreference to FIG. 2. Initially, a file is designated as an anchor file(Block 100), and one or more other files are linked to the designatedanchor file (Block 110). Each linked file is annotated with, forexample, information describing the linked file(s) and any relationshipbetween the anchor file and the linked file(s) (Block 120). The contentof an anchor file is displayed within a user interface along with fileslinked to the anchor file (Block 130). The display of linked files mayinclude the display of the content of the linked files and/or thedisplay of a list of the linked files within the user interface.

According to some embodiments of the present invention, access may begranted to other persons to link files to an anchor file or to any otherfiles in the digital archive (Block 140). The owner of a digital archivemay want to allow others to link files to one or more files within theowner's digital archive. For example, referring to FIG. 4, the linkingof files in two separate digital archives 300, 400 is illustrated. InJill's archive 300, an anchor file 302, which happens to be an image ofJill, is linked to the various content files in Jill's archive 300 (thisis represented by links to a group of content files entitled “Welcome toMy Summer Vacations” 304 and to other content files 308). Within“Welcome to My Summer Vacations” 304 are images organized by year(1976-1978). Under 1977 is a subdirectory entitled “Pictures of Friends”and in this subdirectory is an image of John and David 306.

In John's archive 400, an anchor file 404, which happens to be an imageof high school friends, is linked to the various content files in John'sarchive 400 (this is represented by links to “High School Friends” 402and to other content files 408). In “High School Friends” 402, the imageof John and David 306 is also located. As such, there is a link betweenthe two images of John and David which creates a link between Jill'sarchive 300 and John's archive 400.

When a user touches (e.g., clicks, “mouse overs”, etc.) the image ofJohn and David 306 in either Jill's archive 300 or John's archive 400,the user would see whatever paths existed between the two archives andwhatever paths to content files existed in the respective archives. Forexample, if the user touches the image of John and David 306 in Jill'sarchive 300, the user would see the content files of “Welcome to MySummer Vacations” 304 and other content files linked to by the anchorfile 302, assuming rights and permissions to view these content files isgranted. The user would also see content files in John's archive 400,depending upon what rights and permissions are granted by John.Similarly, if the user touches the image of John and David 306 in John'sarchive 300, the user would see the content files of “High SchoolFriends” 402 and the other content files linked to by the anchor file404, assuming rights and permissions to view these content files isgranted. The user would also see content files in Jill's archive 300,depending upon what rights and permissions are granted by Jill.

According to some embodiments of the present invention, if Jill sendsthe image of John and David 306 to a third party, the image would beaccompanied by whatever rights and permissions Jill is willing to grantto the third party with respect to the content files in Jill's archive300., Thus, the third party would be able to view the content files inJill's archive 300 for which rights and permission were provided byJill. In addition, the third party would be able to see other links tothe received image (i.e., the link to John's archive 400).

According to some embodiments of the present invention, privacy rightsmay be assigned to one or more files within a digital archive (Block150). For example, the owner of a digital archive may assign privacyrights to files linked to an anchor file. The privacy rights may specifywho can access a file linked to an anchor file, and/or may specify whocan access an anchored file. This feature allows others to view fileswithin the owner's digital archive.
